Title: Improvements in or relating to the coagulation of colloidal dispersions
IPC: B29C65/00
Filed: 1937-10-25
Abstract: 504,467. Indiarubber. DU PONT DE NEMOURS & CO., E. I. Oct. 25, 1937, No. 29152. Convention date, Oct. 24,1936. [Class 70] [Also in Group XIII] Aqueous material or artificial colloidal dispersions are coagulated by freezing the dispersion into a shape of which at least one dimension is not more than about 0À1 inch, maintaining the frozen shape below its freezing point until coagulation is complete, thawing the frozen mass so produced and finally separating the coagulum from the liquid aqueous phase by mechanical means. The latter may comprise filtration, centrifuging, washing or application of pressure. The dispersion may be frozen into a band or threads. The former is obtained by the immersion of an internally cooled cylinder or mould having the shape of a desired article in the dispersion and withdrawing it with its adhering frozen film or by forming the film on a rotating cylinder dipping in a bath of the dispersion. Threads of the frozen dispersion arc obtained by extrusion through a nozzle into a refrigerated bath of suitable liquid, such as mercury, or by spraying the material with the aid of a gas jet. The duration and temperature of freezing, preferably below -5‹ C., vary with the dispersion concerned. Natural dispersions specified include natural or synthetic rubber, guttapercha and balata latices. Specification 504,466, [Group IV], is referred to.

Filed: 1966-06-30
Abstract: 1,103,139. Hydraulic braking systems. FORD MOTOR CO. Ltd. 30 June, 1966 [2 July, 1965], No. 29329/66. Heading F2F. A motor vehicle hydraulic braking system comprising a master piston 86 and cylinder 54 assembly having a reservoir 52 integral therewith and a vacuum tank 56 connected thereto. The reservoir 52 is separated into a liquid reservoir 60 and a motor chamber 62, the latter housing an atmosphere suspended piston 68. The piston 68 is provided with a hollow stem 66 which passes through a seal in a partition 58 into the liquid reservoir. The master piston 86 is provided at its outward end with a valve seat 120 which, in the inoperative position of the master piston 86, co-operates with a spring- loaded valve member 128 to allow atmosphere to communicate with the lower face of the piston 68 through apertures 138 in the master cylinder wall and a tube 74. On actuation of the master piston the valve member 128 moves therewith until it abuts a bend 130 in a further valve member 124 to cut off the tube 74 from atmosphere, further movement of the master piston allowing vacuum to be communicated to the lower face of the piston 68 from the vacuum tank 56 to actuate the piston 68. The pressurized liquid passing from the reservoir 60 enters the braking system and is just sufficient to take up the slack in the system. The brakes are then applied by further movement of the master cylinder piston 86. The brake pedal lever 30 co-operates through slots with two pivots, one forming the main pivot when the braking system works normally and the other forming the pivot, to give a greater mechanical advantage, when the reservoir pressurizing piston is inoperative (Fig. 1, not shown). In a modification (Figs. 5, 6, not shown) the reservoir pressurizing piston is vacuum suspended and the valve at the rear end of the master cylinder is of the spring-loaded, flexible, poppet type. The master cylinder is actuated through the brake pedal linkage and a plunger mounted in the master cylinder, the plunger having a lostmotion connection with the master cylinder piston through a spring. Also communication between the reservoir and the master cylinder is controlled by a spring-loaded valve member, the spring of the valve acting between the valve member and the master piston.

Abstract: 341,071. Reproducing recorded sound. WILLIAMS, W. E., Kildare, Ethelbert Road, Bromley, Kent. Oct. 4, 1929, No. 30190. [Class 40 (ii).] Optical apparatus.-A method of reproducing sound by optical means from a record of usual or normal form (i.e. a record which has been produced without any deliberate distortion), comprises the insertion in the path of the light beam of an aperture of such a shape that the displacement or dimensional variation of the beam and the amount of light passing to the light-sensitive device are in non-linear relationship. The aperture may be of lozenge or triangular shape as shown in Figs. 1 and 2 or of double triangle shape as shown in Fig. 3, and the sides of such triangles may be concaved if desired. In another form the aperture may be of general triangular shape with the taper of the sides suddenly increasing at a point say half way from the apex. The record may be in the form of a photographic or other film having recorded thereon a wavy line e, f, Fig. 1, representing the sound trace and dividing the film into two portions of different transparency or reflecting powers or otherwise optically distinguishable. Thus a beam of light reflected from or transmitted through the record reaches the diaphragm containing the aperture as an image of the record with a dark portion g and light portion h or vice versa. Alternatively, the dark portion g may represent an image of a record having one edge cut or serrated in accordance with the sounds. The image j, k, Fig. 2, represents an image formed by light transmitted through a disc or cylinder having a groove recorded on it in such a way as to be more or less transparent than the remainder of the disc or cylinder. Or, the trace j, k may represent the optical image of the sound groove on an ordinary gramophone record. For use with an aperture of double triangle form as shown in Fig. 3, the record may be in the form of a thread in which the sounds are delineated by varying thicknesses of the thread. Alternatively such a record may be formed by a film or flat band of varying width. The apertured diaphragm may be arranged so that the image of the diaphragm may be projected on to the sound groove. The diaphragm may be arranged after a condenser, the concentrated light from which is adapted to be passed through the shaped aperture and thence deflected by a totally-reflecting prism and caused to pass through a lens system which forms an image of the diaphragm on the sound groove. The sound groove is adapted to reflect the shape of the aperture back through the lens system to the photo-electric cell having a further diaphragm arranged with a vertical elongated aperture. The diaphragm provided with the shaped aperture may be formed integrally with the lightsensitive device. Specification 328,317, [Class 40 (ii), Phonographs &c.], is referred to.
